uPVC frames give the best heat-loss figure for the money, in white or woodgrain. Triple glazed uPVC windows are plastic-framed windows fitted with a sealed unit of three glass panes and two gas-filled cavities.
Winter light and glass choice in Derry

Rules for uPVC windows in Northern Ireland
In Northern Ireland, replacement windows must meet 1.6 W/m²K, or a Window Energy Rating of band C or better. Replacing windows or external doors does not need full plans or a building notice, but the work must still comply; enlarging an opening or other structural change needs building control approval.
Planning: Check with your council planning office before changing the style, material or size of windows or doors, and always for listed buildings, conservation areas and flats.
How it works
We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.
- Guide prices published, not hidden
- No pressure: the quote is yours to keep
- Frames, glass and fitting in one contract

Questions from Derry
How long do uPVC windows last?
The Energy Saving Trust gives 20 to 35 years for modern glazing. The sealed units carry their own guarantee, set out on your quote.
Do I need trickle vents?
In England and Wales, if your old windows had trickle vents, the new ones must have vents at least as big, and if they did not, the room must be no less ventilated than before. Scotland and Northern Ireland also require that replacement windows do not make ventilation worse. We size vents on the survey.
